TYPE-FRAME FOR CHASES.

SPECIFICATION forming part of Letters Patent No. 451,625, dated May 5,1891.

Application filed August 8, 1890. Serial No. 361,431. (No model.)

To aZZ whom it may concern:

Be it known that I, NATHANIEL E. SMITH, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented an Improvement in Type-Frames for Chases, of whichthe fol lowing is a specification.

Forms of type are commonly held in a printers chase by blocks of variousshapes and wedges; but much time is often lost in finding and adjustingblocks to fit the various spaces unoccupied in the chase. Printerschases have also been employed of peculiar construction, in which therewere longitudinal and transverse bars operated through and at rightangles to each other by means of screwrods with right and left handthreads, all of which were permanent fixtures in the chase, and which,if employed, required that the usual form of chase be thrown away.

My invention relates to a device for blocking type which is adapted foruse with the ordinary chase; and the same consists of Iongitudinal barsand transverse bars, which together form a frame within the chase, theone set of bars moving in slots in the other set and both sets of barsbeing clamped within the chase by screw-stems having heads and operatingupon disks which bear against the inner face of the chase, and in somecases I employ a brace Where there is a long line of type unsupported,and this brace bears against the chase and one of the longitudinal andtransverse bars and acts to support said bar and assist in securelyblocking the type.

In the drawings, Figure 1 represents a plan view of my improvement. Fig.2 is a longitudinal section of the same at the line as a: of Fig. 1.Fig. 3 is a section in larger size of one of the tightening-screws. Fig.i is an elevation of one of the transverse bars, and Fig. 5 is anelevation of a portion of the chase with my improved brace in theposition it occupies in use.

a represents the printers chase, which is of cast metal in the usualform employed.

1) represents the longitudinal bars, and c the transverse bars, whichtogether form a frame within the chase for receiving and holding theform of type. The longitudinal bars I) are preferably solid and thetransverse bars 0 slotted at c 0 Fig. at, the longitudinal bars 1)passing through the slots of the transverse bars, the transverse barsbeing movable along the longitudinal bars I), and the longitudinal barsI) movable through the slots of the transverse bars a.

(1 represents screw-stems formed with polygonal heads d, and 6represents bearingdisks upon the ends of the screw-stems, the ends ofwhich stems pass through the disks 6 and are upset, so that the stemsand disk are inseparable, but the stems are free to T0- tate within thedisks. One end of each of the longitudinal bars I) and transverse bars 0is perforated and threaded to receive one of the screw-stems (l, which,together with the heads and bearing-disks, form a device for clampingsaid bars Z) and 0 within the chase a at any point desired bysimplyturning the polygonal heads (1 with a wrench to rotate and extendthe stems and cause the disks 6 at one end and the opposite ends of thebars I) c to wedge more tightly within the chase a.

The form of type as set up for printing is to be surrounded by thelongitudinal bars I) and transverse bars 0 either centrally of the chaseor nearer to any portion thereof, and the parts, after being brought upto the type, are clamped, as herein described, and should they not betight enough a slight tap of a hammer will bring the same snugly toplace. In the drawings I have shown an electrotypeblock 13 as clamped bythe bars b c.

The brace shown in Fig. 5 is composed of a central tubular stem f, withright and. left hand threads running in opposite directions from acentral point, and g h represent tubular portions or sleeves internallythreaded and adjustable longitudinally upon the stem f. The outer end ofthe tubular portion h is made solid, and I employ a screw-stem,polygonal head, and bearing-disk similar to those heretofore described,the stem screwing into the end of the tubular portion h and passingpartially through the tubular stem f. This brace is to be employedbetween the central portion of one of the bars b and the chase tosupport and clamp the type, the same being operated and clamped by meansof the tubularportions and the screw-stem set forth.

My improved device is very simple in construction, is Very eflicient inits operation, and possesses the advantage of being adapted for use withthe common printors chase, so that it is not necessary for the printerto buy new chases in order to have an adjustable frame, the frames beingof sizes adapted to fit the chases.

I claim as my invention- 1. The con1bination,with the printers chase, ofthe bars Z), the slotted bars a, through which the bars I) pass, and aclamping-screw passing into one end of each bar and in line with thesame and bearing against the chase for securing such bars in place,substantially as specified.

2. The combination, with the chase a, the longitudinal bars Z),transverse bars 0, and means for clamping the said bars within saidchase, of a brace composed of a stem f, with right and left handthreads, tubular portions 1 and 71, adjustable longitudinally upon thesame, and the screw-stem, polygonal head, and bearing-disk connected toone end of one tubular portion, substantially as and for the purposesset forth.

3. The combination, with the chase a and type-clamping bars, of thebrace composed of a tubular stem with external right and left handthreads, nuts or tubular end portions 9 and it around the tubular stem,the screw (1, and head (1, screwing into the end of the nut (Z andpassing freely into the tubular stein f, substantially as specified.

Signed by me this 1st day of August, 1890.
